PUMP.

Specification of Letters Patent.

Patented July 17, 71906.

Application filed September 13, 1905. Serial No. 278.312.

To all whom, it may concern:

Be it known that I, HIRAM TERRY, a citizen of the United States, residing at Hereford, in the county of Deaf Smith and State of Texas, have invented anew and useful Pump, of which the following is a specification.

This invention relates to pumps, and has for its object to provide a novel construction and arrangement of parts whereby the operating mechanism of the pump is effectually balanced in a simple and convenient manner, so as to require comparatively slight power to manipulate the same.

A further object of the invention is to materially simplify the valve mechanism of the pump and to enable convenient access thereto for repacking the same when worn.

With these and other objects in view the present invention consists in the combination and arrangement of parts, as will be hereinafter more fully described, shown in the accompanying drawings,and particularly pointed out in the appended claims, it being understood that changes in the form, proportion, size, and minor details may be made within the scope of the claims without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawings, Figure 1 is an elevation, partly in section, of a pump constructed in accordance with the present invention and arranged for use in a dug well. Fig. 2 is a similar view showing the invention Fig. 3 is a detail sectional view on the line 3 3 of Fig. 1.

Like characters of reference designate corresponding parts in each figure of the drawin 's.

in the embodiment of the invention as shown in Fig. 1 a suitable platform 1 is supported across the top of the well 2, and a'post or standard 3 is erected centrally upon the platform. Upon the top of the post or standard 3 there is fulcrumed a walking-beam 4, from one end of which depends a pump-rod 5, passing through a suitable opening 6 1n the platform and provided upon its lower end with a. submerged plunger 7. This plunger works in a stationary'submerged upright cylinder 8, which is rigidly connected to a suitable supportfor instance, an upright rod or bar 9, having its lower end seated in the bottom of thewell and its upper end connected to the platform 1, any approved form of brackets 10 being employed to connect'the cylinder tothe supporting-rod. The cylinder 8 is open at its top and closed at its bottom and provided therein with an outlet-port 11, from which leads downwardly an outlet pipe 12. A downwardly-opening foot-valve 13 is provided for the port 11, and the plunger 7 is also provided with a downwardlyopening valve 14, whereby water is taken into the cylinder upon the upward stroke of the plunger and discharged through the .port 1 1 upon the downward stroke of the plunger. An upright discharge-pipe 15 is hung from the opposite end of the walking-beam, preferably by having its downturned elbowed upper terminal 16 received within a bailshaped link or hanger 17, pivotally swung from the walking-beam. This discharge-pipe 15 works vertically through an opening 18 in the platform 1 and at its lower end is provided with a substantially horizontal branch 19, which is connected to the lower end of the outlet-pipe 12 by a hinged joint 20 to permit of the necessary up-and-down movement of the pipes 15 and 19. To balance the weight of the pipe 15 and the water therein, a suitable counterbalancing-weight 21 is carried by the pump-rod 5, said weight preferably being made up of a series of weights of different sizes, which are slipped down upon the rod and supported thereon Within the well above the level of the water.

In the operation of the pump power is applied in any suitable manner to the walkingbeam so as to reciprocate the same in a vertical direction. Upon the downward movement of the plunger the water in the cylinder will be forced downwardly through the pi e 12, thence through the pipe 19, the uprig t pipe 15, and finally out through the discharge spout or elbow 16. I During the upward stroke of the plunger the plunger-valve 14 will of course open, and the water in the well will pass downwardly through the open top of the cylinder, the foot-valve 13 of course being held in its closed position by the weight of the column of water in the dis charge-pipe 15. As the plunger-rod and the plunger are effectually balanced by hanging the discharge-pipe 15 from the walking-beam, the power required to operate the pump is only enough to overcome the weight of the column of water in the discharge-pipe, wherefore a comparatively small power is required for the operation of the present pump, and tllie working of the device is smooth and regu ar.

While the arrangement shown in Fig. 1 is IIO satisfactory for a dug well, the dischargepipe and the plunger-rod are too far apart for use in a bored Well, wherefore I have provided the arrangement shown in Fig. 2 to accommodate the pump to a bored well. In the latter arrangement the same form of platform 1 is provided across the top of the bored well 22, there being the same form of standard or post 13 erected upon the plat- IO form, with the walking-beam 4 fulcrumed upon the top thereof. Beneath the walkingbeam there is a substantially horizontal stationary cross-head 22, fixed to the post or standard, and upon the opposite ends of the r 5 cross-head are mounted the vertically-swing ing levers 23 and 24, which are fulcrumed midway of their ends, as shown at 25 and 26. A connecting-link 27 extends between the outer end of the lever 23 and the adjacent 20 end of the walking-beam, while another link 28 extends between the outer end of the lever 24 and the adjacent end of the walking-beam. The pump-rod 5 is hung from the inner end of one of the levers, (here shown as the lever 2 5 23,) and the upright discharge-pipe 1 5 is hung from the inner end of the lever 24 by means of the hanger 17. The lower end of the pump-rod has the plunger 7, which works in the cylinder 8, and is also equipped With the downwardly-opening valve 14. The outletpipe 12 leads downwardly from the outletport 11 in the bottom of the cylinder and is provided at its lower end with the substantially horizontal branch pipe 29, rigidly se- 3 cured thereto. The lower end of the pipe is terminated short of the pipe 29, and aflexible tube or pipe 30 communicates with the upturned elbowed terminal 31 of the pipe 29 and the lower end of the discharge-pipe 15, the intermediate portion of this flexible pipe being arranged in a coil, so as not to interfere with the up-and-down movement of the pipe 15. By this arrangement of parts the pumprod 5 and the discharge-pipe 15 are brought 4 5 sufliciently close together to be received within the bored well, while the operation of the device is substantially the same as that described for the form shown in Fig. 1 of the drawings, with the exception that the plun- 5o ger is e evated by the downward movement of the adjacent end of the walking-beam, which is brought about by the interposition of the lever 23 and the link 27 between the plunger-rod and the walking-beam.

From the foregoing description it will be understood that the pump of the present invention is effectually balanced in a very simple manner by hanging the weighted plunger-rod and the discharge-pipe from opposite 6o ends of the walking-beam employed to impart the desired reciprocatory movements to the pump-rod, whereby certain elements of the pump are employed to counterbalance one another, and therefore extraneous balancing means are dispensed with. Moreover, the valve mechanism of the pump is materially simplified, as only two valves are required, one for the plunger and one at the foot of the cylinder. The foot-valve 13 is at notime under great pressure and merely opens and closes with the movement of the water, and therefore is not liable to get out of order, while the plunger-valve 14 is conveniently accessible by disconnecting the plunger-rod from the walking-beam and drawing said rod upwardly until the plunger can be reached for repacking the valve. The parts of the present apparatus are reduced to the minimum without in any manner detracting from its effectiveness, and by reason of the balancing of the parts only a comparatively small power is required foroperating the ump.

As a further aid to the easy running and manipulation of the pump each form thereof is provided .with a weight 32, which in the horizontal position of the walking-beam is located centrally above the fulcrum of the beam and is supported. by oppositely-extending arms 33, which have their outer ends secured to the walking-beam at opposite 'sides of the fulcrum thereof. WVhen the weight 32 is rocked to eitherside of the fulcrum of the walking-beam, it will aid in depressing one or the other of the elements 5 and 15. By preference each arm 33 has a hinge or pivotal connection with one end of the weight 32, and its other end has a detachable pivotal connection with one of a series of perforations 34, formed in a walking-beam, whereby the weight 32 may be adjusted vertically, so as to vary the leverage thereof to suit the conditions of the pump.
